Stolen Personal Property At Work

We went on holiday break for the past two weeks and upon returning everyone’s chairs had been taken by two supervisors and cut in half and thrown in the trash. We were never told for 25+ years we couldn’t have chairs or our own personal items in the building. Over half of the chairs were purchased and paid for by employees such as myself. The company claims they were “Unsafe to sit in” when most were brand new chairs. They took 150+ chairs and 130 were cut with a grinder the 20+ were kept because they belonged to the company. We were provided no warning. Went to break with chairs come back with all of them gone.

I went to HR and they will not provide a refund without receipt for a chair bought 8 months ago is there anything the employees as a whole can do about this?
