I’ve worked at a summer camp run by my city for 4 years, I’m my fifth year now. In 2019, I took time off during mandatory training which led me to be downgraded from full time to part time worker, and I was told it was policy. In 2020, the camp was closed due to covid, and since then they have been struggling to find new workers and keep old ones. Now in 2022, there is a shortage of workers and they’ve allowed many people to miss the mandatory trainings without repercussions. Should I contact my union? Is it too late to do anything? I feel like this is unfair, and no one informed me about a change in policy which would now allow employees to miss mandatory training.
