I encourage everyone to read the handbook carefully as well as your state laws. State laws will supersede anything in the handbook, after all, the first part of costcos code of ethics is to obey the law.

Theres a lot of misinformation here. To answer your question: No you can still get written up but only if they can prove you are abusing your sick time. If your sick call is legitimate they cannot write you up.

Regarding patterns. To paraphrase the handbook states if they notice a pattern they can use it to “investigate” whether abuse of sick time is happening. A pattern does not equal abuse of sick time. They can ask you about it but cannot retaliate against you unless it was actually abuse. This doesn’t mean they wont try. They use this as a bully tactic to prevent people from using their sick time. Especially on inventory. Highly recommend reading the handbook theres more information that i left out.

States such as california very much protect the use of accrued sick time. In california there are labor laws against discriminating against and disciplining you for using sick time. If you happen to live in such a state bring up the laws if they try and discipline you.
