Slack operates in the EU and has paying customers in the EU. It also likes to take advantage of anti-competition regulations when convenient: https://slack.com/intl/en-in/blog/news/slack-files-eu-compet...
CEO pay seemed to be $356,952 at time of Slack's IPO.
Maximum fine under GDPR is the greater of 4% annual turnover and $23M. Slack's turnover is too small, which means the maximum fine is $23M, nearly 700% of CEO's basic compensation.
Regulations here have teeth; it's not the United States - and it's a good thing for society that they do.
sadly, the regulators are yet to show that the GDPR has any teeth. Most recently, the ICO gave British Airways and Marriott significant reductions on fines they raised last year.
H&M have been fined £32M. This wasn't hugely far off the 4% annual turnover cap.
Compared to the previous Data Protection Act limits, these fines are definitely significant.
Citing the maximum possible fine here does essentially nothing to convince me of that fact.
TIM were fined 2780% of the CEO's base salary recently.
