This is a Covid-19 situation. We are key workers (UK civil servants). Our normal work can't take place at the moment. So we are doing other jobs in similar roles to cover those off shielding and to keep us working.
The issue is that I work 3 days a week and am being asked to work 1 or 2 days a week on my normal pay, so a bonus of a paid day off though I never know when it is until the evening before. My colleagues who are full-time employees are also being asked to work 1 or 2 days. They get their normal pay too. We are just on the minimum wage so I worked 2 days this week and would have earned about £100, my colleague also worked 2 days and got £250. I know this is short lived we may be back to our normal jobs and days next year but it doesn't seem fair! A fellow part-timer raised this with her line manager and has suffered as a result (not being selected for interview for a promotion).
