She Who Must Be Obeyed sends along a report of the bizarre firings of George (no relation) Eads and Jorja Fox from CSI:

Danica Smith, publicist for both Fox and Eads, told The Associated Press that Fox was fired Wednesday but did not have details. Smith could not confirm whether Eads was fired.
A CBS spokesman said the network had no comment.
Eads didn't show up for work Thursday, the first day of production for the next season, according to the news station and Variety, which posted a story on its Web site Thursday.
The actors were in the fifth of their seven-year contracts.
Though a search was under way for their replacements, it's unclear whether show creators will recast the characters or develop new ones, the reports said.

CSI Files has more news:

fellow supporting actors Gary Dourdan (Warrick Brown) and Paul Guilfoyle (Jim Brass) were "all offered minor raises in exchange for more airtime in a take-it-or-leave-it scenario". The actors were reportedly earning approximately $100,000 per episode but were negotiating for larger salaries.
According to the Hollywood Reporter, CBS asked all cast members to write a letter confirming that they would report to the set on Thursday, the scheduled first day of filming for the season premiere, "Viva Las Vegas". In the past the network has had problems with actors calling in sick in order to give themselves leverage in pay disputes, as several Everybody Loves Raymond cast members did last year.
Fox, despite earlier reports claiming she turned up to the set on Thursday (story), was sacked on Wednesday night after reportedly failing to send in her letter. Eads, who is also said not to have turned in his letter, reportedly turned up to work late on Thursday only to be fired. However, according to Variety sources, Fox did return her letter and "was surprised and mystified when she was fired". Sources close to Eads told the Hollywood Reporter that he too had sent his letter into CBS.
Marg Helgenberger (Catherine Willows) and William Petersen (Gil Grissom) are also looking for bigger paychecks, according to Variety. Both actors failed to report to the CSI set yesterday, "but for health reasons industry insiders said were legit", the trade paper said.

Is it just me, or is firing 2/5 of the main cast of what is, for all intents and purposes, an ensemble drama something of a drastic step?  I can't help but wonder how fired Eads and Fox actually are.
