An ongoing boycott of the Manchester Grand Hyatt San Diego has led to the loss of some group business, according to a hotel spokesman.

But, Kelly Commerford, marketing manager of the Grand Hyatt, said the financial losses have been “negligible” and that the hotel has “lost very little business” as result of the boycott.

The labor group Unite Here has held weekly protests in front of the hotel since last summer, when it was reported that hotel developer Doug Manchester had donated $125,000 in support of Proposition 8. Proposition 8 was a California ballot measure that asked voters to change the California constitution by restricting the definition of marriage and eliminating the right of same sex couples to marry. It passed by a narrow majority of voters during the November elections.

Only two groups have totally canceled meetings at the hotel, Commerford said. Some other groups have moved some of their events off-site in deference to the wishes of their attendees.

When Unite Here launched its boycott in July, it referenced the Doug Manchester Proposition 8 donation, as well as alleged discrimination against hotel workers who, Unite Here claims, are forced to clean more rooms at the Manchester Grand Hyatt than at other Hyatt properties. Unite Here is also maintaining Manchester Grand Hyatt workers have no job security if the hotel should be sold.

Commerford said the hotel has been unfairly targeted, arguing that Manchester’s donation in support of Proposition 8 “is a private act by a private individual.” He also strongly denied the discrimination allegation. Manchester has also stated the hotel is not for sale.

“[The Grand Hyatt] has nothing to apologize for,” said Commerford. “We have a stellar record of supporting diversity as well as gay and lesbian issues and organizations. We’ve hosted gay weddings at the hotel. [Doug Manchester] does not speak for Hyatt, and Hyatt does not necessarily share his views or his values.”
