IT connects the app to the company directory, everyone logs in with the account they already have, and HR&#8217;s system adds and removes people on its own.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That plan works for your permanent staff. It leaves out everyone who is not in the directory. On many frontline sites, that is a large part of the shift: agency workers, seasonal hires, students covering the summer peak. They have no company email, no Entra ID account and often no personnel number at your company. Their phone is their own.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Writing content for these people is the easy part. Identity is harder: how someone gets in, who decides they belong there, and how they get out again. <a href=\"https:\/\/blog.tchop.io\/en\/reaching-temp-workers-frontline-app\/\" target=\"_blank\" rel=\"noopener\">In the first part of this series<\/a> we looked at why a dedicated app is worth it. This part covers how to roll it out.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why temp workers break standard rollouts<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Five things make temps different from the people your rollout plan was written for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>No company email, so no email-based invites, password resets or newsletters.<\/li>\n\n\n<li>No directory or HR record at your company. Agency staff are employed by the agency, not by you.<\/li>\n\n\n<li>Short tenure. More than half of agency assignments in Germany end within three months, <a href=\"https:\/\/statistik.arbeitsagentur.de\/DE\/Statischer-Content\/Statistiken\/Themen-im-Fokus\/Zeitarbeit\/generische-Publikation\/Arbeitsmarkt-Deutschland-Zeitarbeit-Aktuelle-Entwicklung.html\" target=\"_blank\" rel=\"noopener\">according to the Federal Employment Agency<\/a>.<\/li>\n\n\n<li>Their own phone, which changes what you can ask of them and what you can install.<\/li>\n\n\n<li>Several first languages on the same shift.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Each of these needs a decision before launch. If you postpone them, shift leads will solve them on their own, most often with a WhatsApp group.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Choosing how people sign up and log in<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Most sites need more than one login method. Pick them by worker group, and look at how much personal data each one asks for.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Method<\/th><th>Best for<\/th><th>Personal data needed<\/th><th>Watch out for<\/th><\/tr><\/thead><tbody><tr><td>Invite code or QR code per site or shift<\/td><td>Agency staff, first day on site<\/td><td>None upfront<\/td><td>Codes that are shared too widely; account recovery<\/td><\/tr><tr><td>Phone number with a one-time code<\/td><td>Workers without any email<\/td><td>Private phone number<\/td><td>SMS cost, changed numbers<\/td><\/tr><tr><td>Personal email with a login link<\/td><td>Workers who use email<\/td><td>Private email address<\/td><td>Low email use in some groups<\/td><\/tr><tr><td>Personnel number with activation code<\/td><td>Your own payroll staff<\/td><td>Data you already hold<\/td><td>Agency staff have no personnel number with you<\/td><\/tr><tr><td>Single sign-on via your directory or HR system<\/td><td>Permanent staff<\/td><td>None beyond what exists<\/td><td>Excludes everyone not in the directory<\/td><\/tr><tr><td>Shared device or kiosk on site<\/td><td>Workers who decline using a private phone<\/td><td>None on their phone<\/td><td>Logging out at shift end<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Most organisations with a mixed workforce run two or three of these side by side: single sign-on for permanent staff, a code or phone number for temps, and a shared device for people who do not want the app on their own phone.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One gap is rarely discussed: account recovery. If a worker forgets a password and you hold no email address, there is nothing to send a reset link to. Plan for it. Passwordless methods such as one-time codes or login links avoid the problem. Otherwise, shift leads need a way to reissue access on the spot.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">tchop supports single sign-on (OIDC, SAML), login links by email, invite codes, QR codes and phone-number sign-up, and you can combine them in one app.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Deciding who is who<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Before anyone logs in, someone has to decide that they belong. For permanent staff, that is your HR system. For temps, it needs a deliberate process.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There are three common sources. Your HR system feeds permanent staff into the app automatically. Staffing agencies can send lists of the people they place at each site. Or workers can register themselves with a site code, and a shift lead or site admin approves them.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Settle early who creates the account for agency staff: your organisation or the agency. It sounds like an admin detail. It decides who is responsible for the data, who removes the account and who answers when a worker asks what happens to their information.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The first 72 hours<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Whether someone uses the app at all gets decided in the first days. What helps:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Give access at contract signing, not on the first day. A worker who has read the site rules, the dress code and the parking instructions arrives calmer and asks fewer questions.<\/li>\n\n\n<li>Put QR codes where people wait: at the entrance, in the break room, next to the time clock.<\/li>\n\n\n<li>Ask for the language at the first login and show everything in it from then on.<\/li>\n\n\n<li>Prepare welcome content per site and per shift. A night-shift worker at site B needs different information from a day-shift worker at site A.<\/li>\n\n\n<li>Aim for one meaningful action in the first session: read the site rules, confirm the first shift, ask a question.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Preparing welcome content for every site, shift and language is repetitive work, and lean comms teams rarely have time for it. This is a good job for AI agents. tchop lets customers connect their own agents to do it, with the comms team approving what goes out.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Offboarding by design<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Most rollout guides stop at activation. With temps, the end of the assignment matters just as much.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Give every temp account an end date the day you create it. An eight-week assignment means an eight-week account, and when the date passes, access ends without anyone having to remember it. Identity vendors such as <a href=\"https:\/\/www.sailpoint.com\/de\/products\/use-case\/non-employee-lifecycle-management\" target=\"_blank\" rel=\"noopener\">SailPoint<\/a> describe contractor access that stays live after the contract ends as a common risk.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Seasonal workers often come back the next year, so switch their accounts off instead of deleting them. Reactivating takes seconds and avoids duplicate profiles and a second sign-up. Pair that with a retention period, after which the data does get deleted.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Compare that with the WhatsApp group most sites already have. People who left last season are still in it, with every message and every phone number. An app with a defined end of access fixes that by default.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Rollout mechanics that move activation<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Shift leads are the real launch channel. When a shift lead pulls out their phone at the briefing and shows the app, people follow. A poster in the break room does not come close.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">What we see in rollouts that work:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Pick one champion per site or shift, and give them time to help colleagues in the first two weeks.<\/li>\n\n\n<li>Track activation per site and per shift from week one, and talk to the sites that lag.<\/li>\n\n\n<li>Make the first content useful, not ceremonial: shift plans, site rules, the canteen menu, a way to ask a question.<\/li>\n\n\n<li>Decide what the app replaces. If the same message still arrives by WhatsApp, the app becomes optional.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Most published activation numbers come from vendor case studies, and they range from about a third of the workforce to over 90 percent. That spread tells you more about how case studies get picked than about what to expect. Watch your own number per site and how it moves.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Germany: works council, GDPR and agency workers<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In Germany, a rollout that reaches temps has a few extra steps.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The works council has a co-determination right when a technical system is suited to monitoring behaviour or performance (\u00a787(1) No. 6 BetrVG). Read receipts, timestamps and usage analytics are typical triggers. Most organisations conclude a works agreement that covers which data is analysed (often aggregated only), whether use on a private phone is voluntary, which alternative exists for people who decline, and when push notifications may be sent.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Agency workers are a special case. They remain part of the agency&#8217;s workforce (\u00a714 A\u00dcG), but some co-determination rights of the client&#8217;s works council apply to them too, and after more than three months on site they can vote in its elections (\u00a77 BetrVG). Clarify with both works councils which agreement covers them.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">On data protection, both the agency and your organisation may be responsible for a temp worker&#8217;s data once they work in your operations. A joint-controller arrangement under Art. 26 GDPR is a common way to settle this. Data minimisation also argues for login methods that need little personal data, such as site codes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">We have not found a solid answer to one question: does reading the app outside working hours count as working time? Our working assumption is yes, as soon as you expect people to read it. Where reading is voluntary, write that into the works agreement, and have a labour-law advisor look at it before launch.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Three numbers to watch<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Activation within seven days of the start date, per site and shift.<\/li>\n\n\n<li>Reach of important messages per site and shift, not only overall.<\/li>\n\n\n<li>Time between the end of an assignment and the end of access.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The first two show whether people are in. The third shows whether you can let them go without loose ends.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Checklist<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Login methods chosen per worker group, including account recovery.<\/li>\n\n\n<li>Process for adding agency staff agreed with each agency.<\/li>\n\n\n<li>Access at contract signing, QR codes on site, language at first login.<\/li>\n\n\n<li>Welcome content per site, shift and language.<\/li>\n\n\n<li>End date on every temp account; deactivation and reactivation tested.<\/li>\n\n\n<li>Shift leads briefed, one champion per site.<\/li>\n\n\n<li>Works agreement covering analytics, private-phone use, alternatives and push times.<\/li>\n\n\n<li>Data protection roles with agencies clarified.<\/li>\n\n\n<li>Activation and access-end tracked per site.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Planning an employee app for a workforce with many temp workers?
